Abstract :
We simulated the wavelength division multiplexing passive optical network (WDM-PON) prototype with 16 pair of wavelengths. 16 downstream wavelength multiplexed to down streaming 40Gb/s data from optical line terminal (OLT) to optical network unit (ONU) via 1∶16 splitter at the remote node (RN). 16 upstream wavelength are combined at RN from ONU´s and forwarded to the OLT. Amplifier section is placed only at the OLT side hence it pre-amplifying downstream signal and post-amplifying upstream signal. Upstream and downstream results are investigated and analyzed using simulated analyzer and it is found that upstream has better bit error rate (BER) and quality factor (Q-Factor) than the downstream signal.
